Product Description:

The DDS02.1-W050-DL43-01-FW is a digital AC servo drive controller from Bosch Rexroth Indramat in the DDS Drive Controllers series. It is designed for cabinet mounting and acts as the control link between an NC or PLC and a compatible servo motor. During operation, it converts motion commands into regulated current, torque, and speed so a machine axis can follow the programmed sequence with stable positioning. Because the current and feedback loops are closed inside the unit, commanded movement can be carried out with low speed error and smooth transitions between motion segments.

The unit can supply a continuous phase current of 50 A, which supports medium-frame motors during acceleration without pushing the power stage past normal thermal limits. Its enclosure has a rating of IP20, so it is intended for installation inside a protected electrical cabinet. Heat is removed by internal air cooling, and cabinet airflow passes through the heat sink instead of relying on a separate external fan. Command data are handled through a single-axis position control interface, while rotor position is returned through digital servo feedback. This arrangement lets the drive regulate speed accurately, correct position error, and maintain stable control on one mechanical axis.

The allowable ambient operating range is 0 to 45 °C, which suits typical factory conditions without reducing rated output. Storage is permitted from -30 to +85 °C, which helps protect the electronics when the unit is not in service and during transport. Reliable operation is permitted up to 1000 m above sea level before reduced air density begins to affect cooling performance. The drive belongs to Line 02, and it uses Function ID version 01 for its control configuration. These values indicate the assigned control grouping used by the unit within the series.
